The list free_query_feedback_cmds for recycling query feedback cmds was
only used in vn_command_pool when it was a vn_feedback_cmd_pool.
For clarity, refactor and store this list in vn_feedback_cmd_pool
instead and introduce a new struct vn_query_feedback_cmd that references
the feedback cmd and the feedback cmd pool for tracking.
Refactor out the allocation portion of query feedback cmds into its own
function for allocating the new vn_query_feedback_cmd struct.

(cherry picked from commit c3417c5bb8)
All commands that make queries available have feedback cmds batched
and stored during recording. At submission time, for each batch
(SubmitInfo) these feedback cmds are recorded in a cmd buffer that is
appended after the last original cmd buffer (but before
semaphore/fence feedback).
Query reset cmds are deferred as well and also remove any prior feedback
cmds for queries its resetting within the batch.

(cherry picked from commit 6dcf033dc3)
Add feedback commands to write query results into a coherent buffer to
optimize out roundtrip vkGetQueryPoolResults that poll until a result
is available.
Queries are available after vkCmdEndQuery or vkCmdWriteTimeStamp, so
append a vkCmdCopyQueryPoolResults to copy to query results to our
coherent buffer.
The coherent buffer also needs to be cleared after vkCmdResetQueryPool
so append vkCmdFillBuffer.

For query pool feedback, which are variable in size depending on the
query type and being contiguous will allow for simpler copies/clears.

Venus sync feedback design relies on concurrent host device resource
access. To avoid device flush overwriting host writes, we must
suballocate the slots with a minimum size of the buffer alignment.

Unlike fence feedback, commands to update timeline semaphore feedback
slots can't be fully pre-recorded because of the counter value input
for signaling timeline semaphores. To avoid fully recording commands
during vkQueueSubmit, pre-record commands that write a counter value
from a feedback "src" slot to the feedback "dst" slot. Then at
vkQueueSubmit, parse the signal semaphores and write the signal counter
value in the feedback src slot and append the command that writes from
that feedback src slot offset to the command buffer associated with the
signal semaphore.

Refactor out vn_feedback_event_cmd_record2 into a shared functon
that downgrades pipeline barrier commands for non synchronization2
